Houston QB Brian Hoyer sustains his second concussion this season

Houston quarterback Brian Hoyer is doubtful for Sunday’s AFC South showdown against Indianapolis after suffering his second concussion in less than a month.

Coach Bill O’Brien said Monday that Hoyer is following the league’s concussion protocol, and he is also dealing with a strained neck and a wrist problem after being sacked five times in a 27-6 loss to New England. “He took a beating,” O’Brien said.

Hoyer missed a game earlier this season after sustaining a concussion on Nov. 16 against the Bengals.

“Whenever you suffer a concussion like that, multiple concussions within a five- or six-week span, obviously the player himself is concerned about that,” O’Brien said. “And nobody’s more concerned than I am because of my relationship with Brian and his family.”

Browns lose Haden

Cleveland placed star cornerback Joe Haden on season-ending injured reserve because of concussions.

Haden, a Pro Bowl selection the previous two years who signed a five-year, $68-million contract before last season, appeared in only five games this year. He’s been sidelined since sustaining his second concussion on Nov. 1 against Arizona when he was accidentally kicked in the head as he tried to make a tackle.

He received his first concussion on Oct. 11.
