ORCHARD PARK, N.Y. (April 29, 2005) -- Disgruntled Buffalo Bills running back Travis Henry will be disciplined after missing the start of a mandatory minicamp.

Without saying what form of discipline will be applied, head coach Mike Mularkey said Henry is under contract and required to be present for the session that runs through the start of next week.

Henry's absence didn't come as a surprise. The four-year veteran has one year left on his contract but has demanded a trade after losing his starting job last season to Willis McGahee.

Last month, Henry vowed he would not return to practice or play for the Bills.

"I know that he made the statement that he was not going to show. I held out a glimmer of hope, but it did not happen," Mularkey said. "He's under contract and he should be here."

Neither Henry nor agent Hadley Engelhard returned messages.

The Bills continue their attempts to trade Henry after failing to make a deal during last weekend's NFL draft. Team president Tom Donahoe has said he expects Henry to honor the final year of his contract if a trade can't be made.

Buffalo already is seeking Henry's potential replacement, interviewing free agent and former Chicago running back Anthony Thomas.

Henry was a starter since his rookie season and was coming off consecutive 1,300-yard rushing campaigns before being relegated to a backup role in October.

Receiver Eric Moulds was hoping Henry would attend the minicamp.

"I respect his decision," Moulds said. "But at the same time, I'd like to see him here. ... You never know what's going to happen. We might have a guy go down."
