Los Angeles Chargers wide receiver Keenan Allen is listed as a game-time decision for his team's game against the Chicago Bears on Sunday due to a hamstring injury, according to Field Yates of ESPN.

Allen did not practice on Thursday or Friday as a result of the issue.

The veteran logged four catches for 61 yards during the Chargers' loss to the Tennessee Titans last week. On the season overall, he has tallied 44 catches for 564 yards and three touchdowns.

Allen, who played his collegiate football at the University of California, was originally selected by the Chargers in the third round (76th pick overall) of the 2013 NFL Draft.

He played in 15 games during his rookie campaign and was terrific, hauling in 71 receptions for 1,046 yards and eight scores. He took a bit of a step back in his second season, catching 77 passes for 783 yards and four touchdowns, and in 2015 and 2016, Allen appeared in just nine contests combined due to injuries.

The 27-year-old then returned to the field in a big way in 2017, snaring 102 balls for 1,393 yards while reaching the end zone six times, making his first Pro Bowl appearance. He followed that up by finishing with 97 receptions for 1,196 yards and six scores last season.

Los Angeles has been ravaged by injuries all year long and have been one of the most disappointing teams in the league this season, going just 2-5 over its first seven games.

The Bolts have lost three games in a row overall, with all three of their defeats coming against sub-.500 teams.
