In a brief conversation as he was headed to the airport, Texans defensive end Antonio Smith said he was headed to Washington for a visit with the Redskins.

When I asked if he had other visits scheduled, Smith said other teams had interest but he was planning to see how this trip went and where things would go from there. Then he had to catch his plane.

There have been a few other reports about scheduled visits for Smith which include the Titans, Rams and Raiders.

Smith is a guy the Texans like. New head coach Bill O'Brien spoke highly of him during the combine and general manager Rick Smith also praised the defensive end on the same day. Smith would have to come at the right price, though, for a team not willing or able to spend big in free agency.

Smith's leadership and durability were positives for him with the Texans. His pass-rushing numbers weren't gaudy, but he was a powerful force opposite J.J. Watt. Smith was also strong against the run. The 32-year-old was with the Texans since signing as a free agent in 2009.

Free-agent defensive lineman Earl Mitchell is headed to Florida this evening to visit with the Dolphins. ESPN NFL Insider Adam Schefter reports that numbers are in place for that deal: four years at $16 million with $9 million guaranteed.
