Free agent cornerback David Amerson is visiting the Texans on Monday, a source tells Ian Rapoport of NFL.com (on Twitter). It’s the start of a busy week for the former Raider as he has three more trips scheduled. There aren’t many quality free agents available in February, but the Raiders gave Amerson a head start when they released him before the guarantee date on his $5.5MM base salary. Amerson is free to sign with any team and there are several with interest. Amerson’s only other confirmed visit so far was with the Bears, but Rapoport indicates that there were other meetings with teams last week.
