SAN DIEGO -- The San Diego Chargers received bad news Tuesday, with ESPN NFL Insider Adam Schefter reporting that wide receiver Keenan Allen underwent a procedure for a lacerated kidney and has been placed on injured reserve, meaning he is probably done for the remainder of the season.

Allen suffered the kidney injury Sunday against the Baltimore Ravens while hauling in a 13-yard reception for a score. Allen came down awkwardly and remained on the field for several minutes while being attended to by trainers before getting up and being helped to the locker room.

In his third year, Allen was on pace for an historic season statistically. Through eight games, the 23-year-old has 67 receptions for 725 yards and four touchdowns.

With 67 catches, Allen is tied for the second-most receptions through the first eight games of a season in NFL history.

While the Chargers will certainly miss Allen, San Diego has depth at receiver and should find a way to replace his production.

Veterans Malcom Floyd and Stevie Johnson will step in to fill the void on the perimeter. Along with those two, the Chargers will look to get tight ends Antonio Gates and Ladarius Green, along with Danny Woodhead, more involved on third down.

Dontrelle Inman and Jacoby Jones are capable backups who mainly contribute on special teams, but can play meaningful snaps on offense.

And the Chargers could look to promote Javontee Herndon from the practice squad. Herndon can play on the perimeter and as a slot receiver and also provides another option as a returner with Jacoby Jones struggling.

But ultimately, having a quarterback like Philip Rivers makes the loss of a talented player like Allen easier. Rivers completed passes to 10 different receivers last week in a close loss against the Ravens.

Having an accurate passer who has full command of the offense will help the Chargers stay on schedule in the passing game with the team’s No. 1 target not available.
