Allen (hamstring) was listed as a non-participant on the Chargers' estimated injury report Monday.
Allen was forced out of Sunday's 24-19 win over the Raiders due to the hamstring issue and is slated for an MRI on Monday, which should provide further clarity on the injury. It's not surprising to see the star wideout listed as a non-participant Monday, and with the short turnaround, it's likely the Chargers won't push Allen to play in Thursday's showdown with the Chiefs.
