Injury by position (american football)?

I'm going to be playing on the football team next school year and I tore my ACL almost 8 years ago but I was curious how often wide receivers get injured? I'm trying to decide between free safety, the position I'm pretty good at and am much less at risk of being injured. Or wide receiver, position I'm kinda good at but enjoy playing more, but am also more likely to get injured from what I've heard so far. If you can throw in any info you know on the subject it would be greatly appreciated. Thanks.
