Tom Brady fuels speculation about divorce from Gisele Bundchen after latest appearance 

As the speculation around Tampa Bay Buccaneers quarterback Tom Brady and Gisele Bundchen's marriage continues, there may be another sign that the two are indeed parting ways.

A few weeks ago, Bundchen was spotted leaving a gym in Miami without her wedding ring. This weekend, Brady was spotted without his ring.

As he was leaving the team hotel in Pittsburgh on Sunday morning to board the team bus, he was spotted carrying his bag with his left hand and without a wedding ring.

While professional athletes don't typically wear their wedding rings during games, it's unusual that he wasn't wearing his ring before the match.

This comes just two days after he attended New England Patriots team owner Robert Kraft's wedding in Manhattan alone. Brady flew to the wedding alone and then flew right to Pittsburgh to meet up with his team. There was no sight of Bundchen at the wedding or at any Tampa Bay Buccaneers games this season.

Tom Brady compares football life to deployment

It's no secret that Tom Brady's personal life has been the subject of many headlines and discussions this season. When he took an 11-day absence from Buccaneers training camp for personal reasons, many began to wonder whether the quarterback was having marital issues.

Bundchen apparently wasn't happy with his decision to un-retire from the National Football League and return for a 23rd season.

She has also been vocal about the toll that the NFL season puts on their family and how she is left to take care of their family and home. On Monday, on his Let's Go podcast, Tom Brady said that he looks at the start of the NFL season as if he were heading for deployment.

"I almost look at like a football season like you're going away on deployment for the military. And it's like, 'Man, here I go again.'"

He then went on to say that while he has always wanted to create a healthy work/life balance, during the season, his focus is so great that he can't help but spend all of his time on football.

"The reality is, is when it comes down to it, your competitiveness takes over and as much as you want to have this playful balance with the work balance - you're going to end up doing exactly what you've always done, which is why you are who you are."

In his own words, the 45-year-old essentially said himself that he is obsessed with football, something that Bundchen has said for years.
