Paul Kuharsky is reporting on Twitter that Derrick Morgan left practice early today with a left calf injury.

Morgan has been hampered all offseason with these minor tweaks and has missed a lot of practice time.  Of course this is not good considering he is a real key to the Titans being successful on defense this season. 

Check back later for more updates on Morgan's status.

[UPDATE]: Here is what Coach Fisher had to say about Morgan's injury according to John Glennon of the Tennessean:

"Derrick’s had an ongoing calf issue. He had it before he left at the end of OTAs and we just backed him down. He’s not 100 percent. He felt it a little bit, so we just backed him down. He will eventually get back on the field at full speed and 100 percent. When that is, I don’t know. But we’re backing him down just so we don’t risk further injury."
