LINK The Texans worked out quarterback Jesse Palmer (Giants) and receiver Triandos Luke (Broncos), both of whom were waived this week. Receiver P.K. Sam (Patriots) will have a tryout this week. Because the Texans have only three quarterbacks, they're looking at a few who are available in case one of theirs is injured. Rohan Davey and Palmer are the quarterbacks who have worked out so far.
