ORCHARD PARK, N.Y. -- A nagging injury is preventing linebacker Shawne Merriman from getting off on the right foot with his new team, the Buffalo Bills.
Coach Chan Gailey announced Thursday that Merriman will not play against the Detroit Lions (2-6) this weekend, and he is out indefinitely after aggravating an injury to his right Achilles' tendon in his first practice a day earlier.
"It's short-term more than long-term, but we'll just wait and see," Gailey said. "We'll see what happens next week, or it might be the next, I don't know. We're going to get him well. That's the most important thing. Let's get him well before we put him on the field."
Merriman was hurt early into practice during an individual non-contact drill. After dropping back, Merriman pivoted to his left when he pulled up and began hopping in pain. After consulting with trainers, the player limped off the field and was escorted into the team's training facility.
Though he missed practice on Thursday, Merriman was at the facility receiving treatment but did not make himself available to reporters.
The injury is the latest setback for a once-feared pass rusher who earned the nickname "Lights Out" for his hard-hitting style in San Diego.
After registering 39.5 sacks in his first three NFL seasons, Merriman managed just four in his past three years. He missed most of the 2008 season after undergoing reconstructive knee surgery.
His career in San Diego effectively ended last month when the Chargers placed him on injured reserve because of a left calf injury. Merriman also had complained about an injury to his Achilles' tendon.
On Monday, Merriman said he's been working out the past few weeks, but he didn't know if he was in "football shape" yet. He was eager to begin playing.
"Whatever they want me to do, I'm there," Merriman said. "We're all on the same page in getting ready to go play football."
The Bills were counting on Merriman's pass-rush ability to spark a defense that has had difficulty pressuring opposing quarterbacks. The lack of pressure is being blamed on Buffalo managing a league-worst one interception this season, a year after finishing second with 28.
"It's not good," linebacker Paul Posluszny said, when informed of Merriman's status after practice. "It's the opposite of good."
In claiming Merriman, the Bills picked up the remainder of the player's one-year $3.27 million contract.
