Andrews, the 335-pound starter the past three weeks as David Diehl recovers from a hip and hamstring injury, spent a second day in the hospital Friday for treatment of a chronic back condition that cost him the entire work week prior to the Eagles' game last week. He is listed as doubtful for Sunday's game against Jacksonville. Diehl has been ruled out.
"That's a verrrry uncomfortable feeling having needles stuck 7 inches deep into your back! Not as bad as being cut open, but still rough," Andrews tweeted.
Beatty, though, only just got back to playing in spot duty two games ago as an extra tight end after missing seven with a broken right foot.
"Certainly, if you had your druthers, that wouldn't be No. 1 on the hit parade," offensive coordinator Kevin Gilbride said. "Shawn Andrews performed tremendously well for us and was a big part of why we haven't been sacked the last three weeks."
