The Minneapolis Star-Tribune reports the Vikings are uncertain if WR Greg Childs (knees) will come off the PUP list before the regular season. Per beat writer Dan Wiederer, it's "iffy at best" that Childs takes the field in training camp. Beginning the regular season on the PUP list would cost Childs at least six games. Coming off double patellar tendon tears, we're still skeptical Childs will play at all this season.
