Michigan edge rusher and projected first-round pick David Ojabo suffered a left leg injury Friday at Michigan's pro day.No video is available of the injury, but all indications point to a torn left Achilles tendon for Ojabo. The 21-year-old was reportedly injured while taking a pass drop at the pro day after he caught the ball, planted, pushed off and went to the ground non-contact.This is a classic mechanism for a torn Achilles tendon, said Dr. David Chao, ProFootballDoc. Ojabo had to be helped off the field and was later spotted in a boot on crutches with a wrap going up almost to his knee. The hope is he didn't suffer a severe injury, but the wrap and boot are consistent with an Achilles tear, Chao said.Ojabo will be invited to the recheck combines so teams can determine his injury status heading into next season.The injury and timing is certainly not ideal for Ojabo, who finished second on the Wolverines in sacks (11) and tackles for a loss (12).Aiden Hutchison, the projected Top 5 pick, led Michigan in both those categories.An Achilles injury more than likely hurts Ojabo's draft stock, but doesn't necessarily make him undraftable, Chao said. Jeffery Simmons tore his ACL working out for the Draft Combine, but was still selected in the first round of the 2019 draft.Simmons returned to play nine games that season for the Titans and went on to have a productive next two seasons.
