SAN DIEGO -- Two front-line players for the San Diego Chargers are done for the season. Receiver Malcom Floyd and pass-rusher Dwight Freeney will be placed on the season-ending injured reserve Tuesday.
Buddy Baker, Floyd's agent, announced the news via Twitter, and the team later confirmed it.
Floyd has missed the past two games with a neck injury suffered Sept. 15 at Philadelphia. While trying to haul in a Philip Rivers pass across the middle of the field, Floyd took a hard hit from Philadelphia's DeMeco Ryans and Nate Allen on the first play from scrimmage after halftime.
Floyd was taken off the field on a stretcher and transported to a local hospital for further observation. A CT scan on Floyd's neck was negative.
San Diego coach Mike McCoy said last week that Floyd was getting better but the team was meeting with doctors to determine what was best for the 32-year-old receiver's long-term health moving forward.
Freeney, 33, suffered a torn quadriceps muscle during the second quarter of San Diego's win over Dallas last week and opted to have season-ending surgery to repair the issue, according to the team.
Freeney signed a two-year, $8.75 million deal with San Diego in May, which included $4.75 million in guaranteed money. Although Freeney had just half a sack through four games, he had been creating consistent pressure on the quarterback.
Hawkins, 27, was a fourth-round pick by the Tennessee Titans in the 2008 draft. He spent five seasons in Tennessee, totaling 71 catches for 771 yards and a touchdown. Hawkins spent the 2013 training camp with San Francisco but was one of the team's final roster cuts.
At 5-foot-11 and 194 pounds, the Cal product also has some kick return experience and could help out in that area after the Chargers released Fozzy Whittaker last week.
The Chargers needed to add depth at receiver with Floyd done for the season. San Diego currently has four healthy receivers on the roster -- not counting Hawkins -- in Eddie Royal, Vincent Brown, Keenan Allen and Seyi Ajirotutu.
Keiser, a member of San Diego's practice squad, will help fill the void at pass-rusher left by Freeney's injury. Keiser signed as an undrafted rookie free agent with the Carolina Panthers in 2011 out of Stanford. He played in eight games for Carolina after spending his first eight games on the practice squad.
In 2012, he was active for four games with Carolina before finishing the season on injured reserve with an elbow issue. Keiser, 24, totaled 14 tackles, 4.5 sacks and an interception in two seasons with the Panthers.
