MIAMI – Dustin Keller will miss the entire season with a knee injury that leaves the Miami Dolphins without much experience at tight end, a position in which they were counting on an upgrade to enliven their offense in 2013.
Keller seriously injured his right knee during Saturdays preseason game at Houston, two people familiar with the diagnosis said Sunday. They confirmed the extent of the injury on condition of anonymity because the Dolphins made no public comment.
Keller, a former Purdue standout, signed a $4.25 million, one-year contract with the Dolphins in March after five seasons with the New York Jets. His injury represents a significant setback for the Dolphins, who acquired Keller to replace tight end Tony Fasano and help second-year quarterback Ryan Tannehill.
Miami ranked 30th in the NFL last year with 13 touchdown passes, but Tannehill and Keller had clicked in training camp and connected on a 22-yard touchdown pass in the second exhibition game.
Dustin brought a lot to the table for us, Tannehill said. Hes a great player, and its a tough situation. But at the end of the day we have to have somebody step up and play in his shoes.
Keller was carted off the field after taking a hit in the knee from the helmet of tackler D.J. Swearinger, a rookie safety. The play was legal, and Swearinger said he went low because tackling high can lead to a fine.
Minnesotas Adrian Peterson has been cleared for takeoff.
The reigning NFL MVP will make his preseason debut against the San Francisco 49ers this week, Vikings coach Leslie Frazier said Sunday. Peterson sat out the first two games against Houston and Buffalo and hasnt played in an exhibition game since 2011. The Vikings held the star running back out of all four games in the preseason last year while he worked his way back from reconstructive surgery on his left knee.
Frazier wasnt ready to divulge exactly how much Peterson will play at San Francisco.
Bears sign QB
The Bears signed QB Trent Edwards to a one-year contract and waived WR Jerrell Jackson.
Edwards started 33 games in a five-season career with Buffalo, Jacksonville, Oakland and Philadelphia.
Former Notre Dame tight end Tyler Eifert, a Bishop Dwenger graduate, caught three passes for 32 yards Saturday in the Cincinnati Bengals 27-19 win over the Tennessee Titans.
Around the league
Cleveland re-signed free agent rookie running back Jamaine Cook, a move made necessary by injuries to Dion Lewis and Montario Hardesty. Cook was with the Browns earlier this year before he was waived May 21. Cincinnati released linebacker Aaron Maybin, a fifth-year player who signed with Cincinnati as a free agent in January.
Pro Bowl running back Jamaal Charles returned to Kansas City practice with no hesitation despite a lingering right foot strain that caused soreness to travel halfway up his leg.
Denvers Derek Wolfe accompanied his teammates on their flight home after being whisked from the field in an ambulance after a scary scene in which he lay prone on the field for a few minutes following a hit to his head Saturday night. Medical staff strapped him to a backboard and sent him to a hospital for evaluation of a possible cervical spine injury. X-rays, CT scans and MRIs were all negative, however.
Tennessee wide receiver Kendall Wright will miss Saturdays preseason game with Atlanta after an MRI exam shows he sprained his right knee. Coach Mike Munchak said he hopes the receiver will be back for the season opener Sept. 8 at Pittsburgh.
