Greg Desrosiers: 40 Time, NFL Draft, Age, Highlights, Injury and Stats

Greg Desrosiers Jr. has become an intriguing name for NFL fans after earning an opportunity with the Los Angeles Chargers as an undrafted free agent following the 2026 NFL Draft. The former Memphis running back brings a combination of speed, versatility and experience to a crowded Chargers backfield.

His path to the NFL was not straightforward. Desrosiers dealt with injuries during his college career, including a foot problem that affected his 2025 season. However, he still produced a strong campaign and showed enough athletic ability to earn an NFL opportunity.

Here is everything to know about Greg Desrosiers, including his 40 time, NFL Draft status, age, highlights, injury history and college stats.

Greg Desrosiers 40 Time

Greg Desrosiers Jr. recorded a 4.52-second 40-yard dash at his pro day, according to RotoWire. DraftScout lists his estimated 40-yard time at approximately 4.55 seconds, with a range of 4.50 to 4.60 seconds.

His other pro-day measurements also showed solid athleticism. Desrosiers measured around 5-foot-10 to 5-foot-11 and weighed approximately 200-202 pounds. His workout numbers included a 34.5-inch vertical jump, a 121-inch broad jump, a 4.21-second shuttle and 18 bench-press repetitions.

The 40 time is particularly important for Desrosiers because his game relies on quick acceleration, decisiveness and the ability to create explosive plays.

Was Greg Desrosiers Drafted?

No. Greg Desrosiers was not selected in the 2026 NFL Draft.

Instead, the Los Angeles Chargers signed him as an undrafted free agent shortly after the draft. CBS Sports reported that Los Angeles added Desrosiers on April 25, 2026.

His road to an NFL roster will be challenging because the Chargers already have several running backs competing for opportunities. However, his college production and versatility give him a chance to compete for a roster or practice-squad position.

The Chargers’ decision to sign him also reflects his ability to fit a zone-running system. He ran most of his 2025 rushing attempts from zone concepts and was praised for his patience and decisiveness as a runner.

Greg Desrosiers Age

Greg Desrosiers Jr. is 25 years old as of August 2026, according to CBS Sports. He was born in Lawrence, Massachusetts, and played his college football at Memphis after beginning his career at UMass.

His college career took place over several seasons because of his transfers and redshirt status. That experience helped him enter the NFL with a mature understanding of the running back position.

Greg Desrosiers College Career

Desrosiers started his college career at Massachusetts before transferring to Memphis.

At UMass, he showed explosive ability as a complementary running back. In 2022, he rushed for 210 yards and two touchdowns on 44 attempts. In 2023, he improved significantly, producing 301 rushing yards and four touchdowns on only 37 carries while averaging an impressive 8.1 yards per attempt.

He transferred to Memphis for the final two seasons of his college career.

In 2024, Desrosiers appeared in eight games and rushed for 228 yards and three touchdowns on 31 carries. He also contributed 21 receptions for 175 yards and four receiving touchdowns.

That receiving ability became an important part of his profile.

Greg Desrosiers Injury

Injuries were one of the biggest concerns surrounding Desrosiers during the NFL draft process.

He dealt with a collarbone injury in 2024 and played through a foot injury during the 2025 season. The foot issue limited him during his final college campaign, although he still managed to rush for 563 yards.

Desrosiers underwent foot surgery before Memphis’ bowl game and was still working his way back to full health during the pre-draft process.

At Memphis’ pro day in March 2026, he acknowledged that he was still recovering and working toward 100 percent health. He also said NFL teams understood that he had played through the injury during the 2025 season.

The injury history likely contributed to uncertainty around his draft stock, but it did not prevent him from receiving an NFL opportunity.

Greg Desrosiers Highlights

One of the best examples of Desrosiers’ ability came during his first season at Memphis against Tulane. He scored three touchdowns, a performance he later identified as the game that best showed what he could do when healthy.

His 2025 game against FAU was another standout. He exploded for 204 rushing yards and three touchdowns, including a 90-yard scoring run.

His NFL preseason has also given fans a glimpse of his explosiveness.

During the Chargers’ 2026 preseason matchup with the Steelers, Desrosiers produced a 33-yard run, while another play showed him gaining 15 yards with his shiftiness.

In the Chargers’ preseason game against the 49ers, he carried the ball four times for 21 yards and was praised for looking quick and explosive.

Greg Desrosiers NFL Opportunity

Desrosiers entered the NFL with plenty to prove. The Chargers have significant competition at running back, meaning he needs to demonstrate that he can contribute in multiple areas.

His receiving ability could help him. In 2025, he caught 32 passes for 228 yards and a touchdown. He has also handled kickoff-return duties during his college career.

Special teams could therefore become an important route to earning a roster spot.

His ability to run inside, operate in a zone scheme, catch passes and contribute on special teams gives him multiple ways to make an impression.

What Makes Greg Desrosiers Interesting?

Desrosiers’ biggest selling point is his combination of explosiveness, patience and versatility.

He is not simply a straight-line runner. The Chargers have highlighted his ability to make decisions quickly in zone concepts and create yards when the blocking does not provide a clean path.

He also forced missed tackles at a strong rate during his final college season. Sports Illustrated’s Chargers analysis noted that he had a missed-tackle-forced rate of about 0.303 in 2025.

That ability could become valuable if he gets opportunities in the NFL.

Final Thoughts

Greg Desrosiers’ journey from UMass and Memphis to the NFL has been shaped by both production and adversity. He was not drafted in 2026, but the Los Angeles Chargers gave him an opportunity as an undrafted free agent.

His 4.52-second reported pro-day 40 time, 1,302 career rushing yards, 16 rushing touchdowns and ability as a receiver make him an intriguing developmental running back.

The biggest question remains his health and ability to separate himself from a crowded Chargers running-back group. If he stays healthy and continues making explosive plays in preseason action, Desrosiers could turn his UDFA opportunity into a longer NFL career.
