NASHVILLE, Tenn. -- After missing nine OTA workouts because of school obligations at the University of Washington, running back Bishop Sankey was back with the Tennessee Titans on Thursday and took part in his first workout since rookie orientation.

Sankey, a second-round pick, is trying to make up for lost time, even though he had an iPad playbook with him on which the Titans sent updates, by getting acclimated to on-field work in the backfield.

"It was a little tough because you just want to be here and get in the mix, and sometimes you feel like you're falling behind," Sankey said. "But today, it felt good just getting back in the swing of things.

"But at times it was a little tough, just being clear across the country and everyone else is here getting their work in."

Titans coach Ken Whisenhunt said he liked what he saw of Sankey on his first day, even though he did look a bit rusty at times.

"It's pretty apparent watching him today in practice he's a good runner, he's got a good feel," Whisenhunt said. "You can see that with the way he moves. He's in good shape. It's just the mental part of it.

"I guess the best way to say it is, mentally he's in good shape, but when you get on the field and things start moving quickly the normal thing to do is have a little bit of hesitation, and you see that."

Sankey admitted that there was a mental error or two on the first day, but he knows those will be corrected in time.

"One or two times, I did slip up and didn't run the right play," Sankey said. "But again, I think that'll be corrected easily with time and the more reps I get, it'll be corrected."

The school rule that kept Sankey at Washington for most of the OTAs also kept former Huskies teammate Travis Coons away as well.

Coons is battling Maikon Bonani, who was in camp last season with the Titans, to replace veteran Rob Bironas as the Titans' kicker. Coons signed with Tennessee as an undrafted rookie.

--Defensive end Jurrell Casey, making the switch from a 4-3 defensive tackle to a five-technique end (as well as some other assignments as the defense is installed), is in preliminary talks with the Titans about a contract extension.

Casey, a third-round pick in 2011, has blossomed into the Titans' best defensive player, with 10 1/2 sacks a year ago. Casey said he wants to stay in Tennessee.

"That's always great that they see me and see my value and that I can help this team and do good things," Casey said. "I would love to be here long term, so if we're able to get something done, great."
