"That was pretty tough. You work all summer and have a chance to come in and play and help the team out and that happens," Sanford told stlouisblues.com. "But it's hockey, it happens. It's been a long year, but it's good experience so now I know how to handle that type of stuff."
Now that he's been activated from injured reserve, Sanford said he is looking to getting back into action with San Antonio.
"I think it will be good for me," he said. "I haven't played in almost a year now. It's crunch time for us this time of year, so to have this time to go get some games down there, to get that conditioning back and get that timing back is really big for me."
Sanford joined the Blues last season as part of the trade that sent Kevin Shattenkirk to the Washington Capitals. The Blues also acquired a first-round pick in 2017, conditional draft picks and prospect Brad Malone in the deal.
In 13 regular-season games with the Blues last season, Sanford scored two goals and three assists. He also made four appearances in the Stanley Cup Playoffs.
