Detroit Lions running back Reggie Bush sat out of practice on Thursday as he continues to recover from an ankle injury.
The Lions are currently in London ahead of their clash with the Atlanta Falcons at Wembley Stadium on Sunday.
"I'm going to do everything I can to be out there on the field on Sunday," Bush told WXYT-FM.
The 29-year-old was limited in practice on Wednesday and he continues to be a concern for coach Jim Caldwell, with Joique Bell expected to step in if required.
Meanwhile, Detroit did receive a fitness boost as Calvin Johnson was seen cutting and running routes during practice after suffering with an ankle injury of his own.
