Free agent defensive end John Abraham sent out two tweets on Saturday that have since been deleted that said "retiring 13" and "Done."

However, Abraham, who turns 35 on Monday, is not ready to leave football just yet, per TitanInsider.com.

The free agent visited with the Tennessee Titans on Thursday and Friday, but has yet to find a landing spot this off-season since leaving the Atlanta Falcons. The Falcons opted for Osi Umenyiora in free agency as their situational pass rusher.

Abraham has 32.5 sacks the past three seasons and certainly could help a team like the Titans or someone else as a pass rush specialists. The matter could be how much money Abraham is willing to play for in 2013.
