The Atlanta Falcons don't open training camp until Thursday, but linebacker Lofa Tatupu has already been added to the walking wounded.
"Lofa sustained a pectoral injury while working out recently (Thursday)," coach Mike Smith told the team's official site. "At this point, we do not know the extent of the injury, but we expect to have more information early next week."
The Falcons signed Tatupu to a two-year, $5.75 million deal in March with hopes he would compete with Akeem Dent for the starting middle linebacker spot left vacant by Curtis Lofton's departure. Tatupu worked with the first-team defense through much of the offseason program.
Tatupu missed all of 2011 after a pair of knee surgeries, but said he could have played. After he wasn't picked up by anyone, Tatupu considered retirement, according to The Boston Globe. He spent his first six seasons with the Seattle Seahawks, who drafted him in the second round in 2005.
The Falcons have promised an update, so we'll keep on top of this one.
Update: Tatupu is scheduled to see Dr. James Andrews on Monday to learn the severity of the injury, according to the Atlanta Journal Constitution.
