In a surprising development, the Tennessee Titans have expressed their interest in interviewing Antonio Pierce for their head coaching vacancy. This news comes hot on the heels of reports that the Las Vegas Raiders are considering keeping Pierce as their permanent head coach, following his impressive interim stint with the team.

According to Ian Rapoport of NFL Media, the Titans have formally requested permission to speak with Pierce about their head coaching position. Pierce, who took over as interim head coach for the Raiders after the firing of Josh McDaniels, guided the team to a commendable 5-4 record during his tenure.

Pierce's success in turning around the Raiders' season did not go unnoticed, as several players on the team have publicly voiced their support for keeping him on board as head coach. However, with the Titans now in the picture, it remains uncertain whether Pierce will be the "bird in the hand" for the Raiders' coaching vacancy.

The Titans, who recently parted ways with Mike Vrabel, have not limited their quest to just Pierce. They have also requested permission to interview Aaron Glenn, the current defensive coordinator for the Detroit Lions. This indicates that the team is thoroughly exploring their options to find the best fit for their coaching staff moving forward.

As the Titans' coaching search continues, the demand for Pierce's services appears to be increasing beyond what the Raiders might have initially anticipated. While it remains to be seen which direction the Raiders will ultimately go in their search for a head coach, Pierce's skill and positive impact during his short stint has undoubtedly caught the attention of other teams.

It remains to be seen how the situation will unfold, but one thing is clear: Antonio Pierce's name has become a hot topic in the coaching carousel this off-season.
