Earlier on Monday, it was revealed that Oakland Raiders wide receiver Hunter Renfrow had suffered a broken rib and a punctured lung during his team's loss to the New York Jets on Sunday.

Later, Raiders head coach Jon Gruden told reporters that Renfrow may be done for the remainder of the season pending further tests, according to Ian Rapoport of NFL Network.

This would be a pretty significant blow for an Oakland receiving corps that is not all that deep as it is.

Renfrow, who played his collegiate football at Clemson, was selected by the Raiders in the fifth round (149th pick overall) of the NFL Draft back in April and was initially expected to be an auxiliary piece behind Antonio Brown and Tyrell Williams.

However, the Raiders ended releasing Brown just before the regular season began, thrusting Renfrow into the spotlight as one of Derek Carr's top options in the aerial attack.

On the season overall, the rookie wideout has logged 36 catches for 396 yards and a couple of touchdowns, with 22 of his receptions coming since over his last five games.

Should Renfrow be sidelined for the rest of the year, the Raiders' receiving corps will get that much thinner, and their playoff hopes will take a bit of a hit.

Oakland's 34-3 defeat at the hands of the Jets was a massive setback for the club, especially considering that New York was supposed to be one of the easiest games on its remaining schedule.

Now sitting at 6-5, the Raiders will head on the road to battle the Kansas City Chiefs next Sunday before returning home to host the Tennessee Titans on Dec. 8 in a contest that could have major playoff implications.
