LONDON -- A few thoughts on the Detroit Lions' 22-21 win over the Atlanta Falcons at Wembley Stadium in London.

What it means: The Lions spent the first month of the season trying to find a field goal kicker. Now it appears they have one. Matt Prater made a 48-yard field goal as time expired to give the Lions their second come-from-behind win in as many weeks -- this after Prater missed a 43-yard attempt that was waived off because of a delay of game penalty. The Lions have found a way to win games they really have had no business of winning and have put themselves in a good position at the halfway point of the season. Prater’s field goal capped a 21-point second-half comeback for Detroit.

Stock watch: Rising -- Golden Tate. The receiver once again had a massive game with seven catches for 151 yards and a touchdown. He has become a star for the Lions over the past month with his fourth 100-yard game in the last five contests. Theo Riddick is also rising. With Reggie Bush out, Riddick once again became a playmaker with three carries for five yards and eight catches for 74 yards and a touchdown. He might be finding a role in Detroit’s offense even when Bush returns.

Falling -- health. The injuries are starting to become an issue for Detroit. The Lions lost Nick Fairley on Sunday and were already without Calvin Johnson, Bush, three tight ends and their starting right tackle. Tough to win games that way. Yet the Lions did.

Defensive line depth is dwindling: C.J. Mosley was suspended, and Fairley injured his knee in the first half. Atlanta then ran right at the middle of the Detroit defensive front and rookie Caraun Reid. Mosley’s suspension really hurt the Lions’ depth, to the point they had to put the undersized Darryl Tapp in at defensive tackle for some plays during the second half.

Game ball: Tate. He once again turned in a big performance and helped the Lions pull out another come-from-behind win in the second half. If Detroit ever gets to full health, it could have one of the most potent offenses in the league. But right now, Tate is the reason the Lions are 6-2 heading into the bye.

What’s next: The Lions are off for a week -- something Detroit needs desperately considering all its injuries -- before facing Miami at home in Week 10.
