MIAMI -- Miami Dolphins tight end Dustin Keller will miss the entire season because of a right knee injury, a person familiar with the diagnosis said Sunday. The person confirmed the extent of the injury on condition of anonymity because the Dolphins hadnt commented. Keller was hurt in the second quarter of Saturdays exhibition game at Houston. His leg bent unnaturally when he was tackled by D.J. Swearinger on an incompletion, and he was carted off the field. Keller signed a $4.25 million, one-year contract with the Dolphins in March after five seasons with the New York Jets. He had hoped to parlay a big season in 2013 into a multiyear deal. His injury represents a significant setback for the Dolphins, who signed Keller to replace tight end Tony Fasano and help second-year quarterback Ryan Tannehill. Keller and Tannehill had clicked in training camp and connected on a 22-yard touchdown pass in the second exhibition game. The injury leaves the Dolphins without an experienced tight end. Options to replace Keller include fourth-round draft pick Dion Sims, who has had a good camp, and Michael Egnew, who played in only two games last year after being drafted in the third round. Keller has 17 career touchdown receptions, but he played in only eight games in 2012 because of hamstring and ankle injuries. A. J. Cann Jersey .

Asked by Sky Sports F1 to assess their pole chances on Saturday, Vettel said: It depends what the others are doing, but I think if we get everything right we could be closer.Practice Two reportBut then it is only Friday today so I wouldnt stress. I wouldnt put too much importance in the times today. After eight successive Mercedes qualifying one-twos, Ferrari head into Saturday knowing they are still likely to qualify with one car on the front row after Lewis Hamilton collected a five-place grid penalty.But predictions for how the grid could shape up for Sundays race are likely to be revised in any case should rain forecast for Saturday in Shanghai hit during the qualifying hour.The weather forecast for tomorrow is a bit uncertain, but we can still improve, added Vettel. The balance of the car was not yet where I want it to be, but overall I think it was a decent day.Despite setting the outright pace in P2, team-mate Kimi Raikkonen was not completely satisfied with the handling of his Ferrari either and suggested the supersoft tyre - the compound he set his fastest lap of 1:36.896 on - was the only one which he had been happy with.

But the softs didnt feel very good, the supersoft was the best, but it is too early to say.Not an easy day, maybe the wind or whatever, it felt very slippery.
