Coach Matt Nagy revealed that Jackson injured his hamstring during a recent workout but added, 'It's something that we're not overly concerned [with]." The NFI list is for players who sustain an injury outside of their team facility.
Jackson has been durable since being selected by the Bears in the fourth round of the 2017 draft out of Alabama, starting 62 of a possible 64 regular-season games over four seasons. The only two contests he missed came in the final two weeks of the 2018 campaign after he hurt his ankle when he was tackled while returning an Aaron Rodgers interception.
Ifedi tweaked his hip flexor during a conditioning test Wednesday morning in advance of the Bears' first training camp practice. The 6-5, 340-pounder has started 63 of a possible 64 games the past four seasons with the Seahawks (2017-19) and Bears (2020).
"We're checking him out and just seeing where things are," Nagy said. "We feel pretty good about it as far as sometimes you get those in these conditioning tests.
"I know Germain's been working hard in the offseason, so it's just unfortunate. But I think he'll be OK."
Jackson and Ifedi both can return to the active roster and begin practicing at any time during training camp.
Rookie left tackle Teven Jenkins also sat out Wednesday's workout with back tightness that he developed during rookie camp this past weekend. The second-round pick from Oklahoma State is considered day-to-day.
Nagy predicted that the greatest challenge Jenkins will face when he returns to action will be "most likely in the pass game, making sure with those sets and understanding Juan [Castillo's] techniques that he uses. Taking the techniques that he learned in OTAs, putting the pads on and doing it against some pretty good players there on the edge with Robert [Quinn] and Khalil [Mack] and those 1-on-1s all the time.
"I think the run game will be a little bit easier for him, and I do believe that is one of his strengths from watching tape," Nagy said. "I think he's really good in the run game. And then also, too, the communication with all the IDs and the protection-checks."
