Los Angeles Chargers wide receiver Keenan Allen didn't practice in Thursday's training camp for a previously undisclosed injury. The Athletic's Daniel Popper noted that Allen “banged up his knee in the last joint practice, with the Rams two weeks ago.”

ESPN's Adam Schefter shed light on the situation, as he reports that Allen suffered an ankle injury in practice. The injury isn't considered to be major, “but could knock him out of the Chargers’ remaining three preseason games,” according to Schefter. He should be available for the regular-season opener against the Indianapolis Colts.

Allen previously left last Thursday's practice with an undisclosed injury. He returned a day later.

Allen has had a good training camp in 2019, his seventh with the Chargers. Anthony Lynn said on Tuesday, via the Chargers official website:

“Consistency is what I see from Keenan. “He’s very consistent. He’s in great shape. His intangibles have actually, I feel like, improved. He leads by example. He’s a leader on this team, so [I’m] glad we have him.”

After two days of training camp, Allen noted that he feels as good as he ever.

“I feel amazing,” Allen said, per the Chargers official website. “It’s year seven, [the] best I’ve felt and most I’ve worked in the offseason up to this point.”

In 2018, Allen went to his second-straight Pro Bowl. In 16 games played (14 starts [injury]), Allen tallied 97 receptions for 1,196 yards and six touchdowns.

The year before, he set career highs in receptions (102) and receiving yards (1,393) and added six touchdowns in the process.
