Donald Parham, Jr. is currently undergoing tests, imaging and evaluation for a head injury at UCLA Harbor Medical Center, according to the Los Angeles Chargers.

He is in stable condition.

Parham hit the back of his helmet on the turf while attempting to catch a fourth-down pass in the back of the end zone early in Thursday night's loss to the Kansas City Chiefs.

The Los Angeles Chargers went for it on fourth down while in field goal range three times in the team's 34-28 overtime loss to the Kansas City Chiefs on Thursday night.

They failed on each attempt.

"From where my mindset is, I know that the quickest way to win a game like that is to score touchdowns, not field goals, especially considering who's on the other side," Brandon Staley said after the loss.

"To me, when you feel like you're in an advantage situation, when you don't feel like it's a gamble, and you feel like this is an advantage for you, then that's going to be our mindset. I don't think that any decision that I made tonight was a gamble. We felt like it was an advantage situation for us. That's why we did it. If we didn't feel like that was the case, then we would have kicked a field goal or we would have punted. That's the way that we're going to do things around here. I know that our team embraces that mindset. We're going to continue to do it every game we play moving forward."

The Los Angeles Chargers have placed Keenan Allen on the reserve/COVID-19 list.

The Chargers will face the New York Giants on Sunday.

Brandon Staley said that Allen's status "is day-to-day right now, and hopefully we'll have some good news on him in the next few days."

Allen is reportedly vaccinated, so he will need two negative tests 24 hours apart and to be asymptomatic for 48 hours before he can return.
