It’s the worst-case scenario for Dustin Keller: The Dolphins tight end is lost for the season — and possibly longer — to a catastrophic knee injury.
And a veteran replacement anywhere near his caliber doesn’t appear on the horizon.
An MRI indicated Keller tore three ligaments and potentially also suffered nerve damage — a potentially career-threatening injury — in Houston on Saturday night. The team had not made a roster move as of Sunday afternoon, but it’s a formality that he will be put on a year-ending injured list.
Without Keller, the Dolphins have no real veteran presence at the position. While the team has drafted a tight end in each of the past three seasons, Dion Sims, Charles Clay and Michael Egnew have not yet established themselves as dependable deep-seam threats.
“We have other guys who have caught the ball down the middle,” Dolphins coach Joe Philbin said late Saturday. “We have some big targets. Egnew’s a big man. Dion Sims is a big man. Clay has caught the ball down the middle before. We’ll adjust.”
The Dolphins placed some preliminary calls for a potential replacement Sunday, but the feeling by many around the league is they will probably go largely with what they have at the position.
Peterson set to play
Adrian Peterson has been cleared for takeoff. The reigning NFL MVP will make his preseason debut against the San Francisco 49ers this week, Minnesota Vikings coach Leslie Frazier said Sunday. Peterson sat out the first two games against Houston and Buffalo and hasn’t 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.
Wright to miss game
Titans wide receiver Kendall Wright will miss Tennessee’s third preseason game with Atlanta after an MRI exam shows he sprained his right knee in a loss at Cincinnati. Coach Mike Munchak said Sunday he hopes the receiver will be back for the season opener Sept. 8 at Pittsburgh.
Bengals release Maybin
The Cincinnati Bengals released linebacker Aaron Maybin, a fifth-year player who signed with Cincinnati as a free agent in January. Maybin was Buffalo’s first-round pick out of Penn State in 2009. The Bengals also waived receiver Tyrone Goard and cornerback Troy Stoudermire, both undrafted free agents.
Derek Wolfe says he’ll be back on the field soon. The Denver Broncos hope fellow starters Champ Bailey, Wes Welker, Louis Vasquez and Stewart Bradley will be there with him. All of them were hurt in Denver’s 40-10 preseason loss at Seattle on Saturday.
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 and neck. X-rays, CT scans and MRIs were all negative.
Bears sign quarterback
The Chicago Bears signed quarterback Trent Edwards to a one-year contract and waived receiver Jerrell Jackson. Edwards has started 33 games in a five-season career with Buffalo, Jacksonville, Oakland and Philadelphia. The former Stanford quarterback has more than 6,000 yards passing with 26 TDs.
