It's officially an 0-2 start in Dan Campbell's inaugural season as head coach for the Detroit Lions and, two weeks in, he's already being forced to take some lumps. After nearly mounting an impressive comeback against the San Francisco 49ers in the regular-season opener, the Lions got run out of Lambeau Field by Aaron Rodgers and the Green Bay Packers, and the game isn't the only thing they lost on Monday night. Ifeatu Melifonwu, the team's rookie third-round pick, suffered an injury that is expected to sideline him for several weeks.

The exact timeline for his return is to be determined and/or if he's headed to injured reserve, but Campbell made it clear after the game that they'll have to move forward without their first-year cornerback -- for what sounds like multiple weeks.

"Yeah, it's a bad one," Campbell said, via Kyle Meinke of MLive.com. "Looks like he will be out for a little bit."

It's quite the blow to the Lions secondary, considering Melinfonwu was named starter following the loss of former first-round pick Jeff Okudah, who suffered a torn Achilles in the loss to the 49ers. The Lions have now effectively lost two starting cornerbacks in as many weeks, and they'll get no respite from the football gods with Lamar Jackson and the Baltimore Ravens next on their schedule.

The injury to Melinfonwu occurred on a play that saw him matched up with All-Pro receiver Davante Adams in the third quarter, when Adams streaked down the sideline for what would become a 50-yard completion from Rodgers. Melifonwu went to the ground and was immediately evaluated by trainers, and while he wasn't ruled out of the game -- listed as questionable to return -- he never re-entered the contest.

And it's now unclear when he'll take the field again.
