EDEN PRAIRIE, Minn. -- The Minnesota Vikings' injury woes extend way beyond MVP running back Adrian Peterson.
Minnesota (3-9-1) placed tight end Kyle Rudolph on injured reserve Monday, ending his season when the team determined he wouldn't be able to return to practice in time to play this season, coming off the broken foot he suffered on Nov. 3 against the Dallas Cowboys.
The Vikings originally gave Rudolph a four-to-six week timeframe for recovery. Frazier was hopeful Rudolph would be back at practice this week, but he wasn't able to make enough progress for a return.
"Kyle Rudolph, we were hoping we'd be able to get him up and practicing this week," Frazier said Monday. "That's not going to be the case. We made the decision that we're going to put him on injured reserve, so he'll be down for the rest of the year."
Rudolph was expected to another big year for Minnesota after winning the Pro Bowl MVP award following last season. He finished with 30 catches for 313 yards and three touchdowns in eight games this season as the revolving door at quarterback led to inconsistency in the passing game.
Minnesota also decided receiver Greg Childs, on the Physically Unable to Perform list, won't make it back this season as he tries to return from bilateral patellar tendon tears in both of his knees. The Vikings had to decide whether to activate Childs to the active roster, but he will stay on the PUP list and miss the rest of the regular season now.
The 2012 fourth-round pick out of Arkansas has yet to play in a game for Minnesota. He suffered the patellar tendon tears two weeks into his rookie training camp last year.
"He did a good job in his return, did some things we were glad to see," Frazier said. "But at this point, made the decision that he's going to be on the PUP list."
Peterson suffered a sprained right foot in Sunday's game and is still undergoing further tests. Backup Toby Gerhart has a hamstring injury.
Also from Sunday's game, tight end John Carlson suffered a concussion, right guard Brandon Fusco is dealing with a knee strain and cornerback Xavier Rhodes has a sprained ankle. Frazier classified Carlson and Fusco as day-to-day.
Frazier said quarterback Christian Ponder has passed his concussion testing.
"I did find out this morning, he did pass everything," Frazier said. "So he's cleared now. We'll sit down today as a staff and talk about how we want to go forward at the quarterback position."
Frazier said cornerback Josh Robinson, out after suffering a fractured sternum on Nov. 17, won't be ready to return this week.
"The word I got today, he's making some progress but not to the point where he's going to be ready for this ballgame," Frazier said. "So, we'll have to make a decision on how we want to go forward with him, as I learn a little bit more about the likelihood of his playing maybe in the following game that will determine what we do with him going forward."
Frazier added the team might need to add help depending on the health of Peterson, Gerhart and Rhodes.
"We'd be pretty thin going into a ballgame with three corners or maybe four corners," Frazier said. "We'll see what happens with the running back position. We'll definitely have to do something somewhere depending on what happens or who we may or may not have."
Frazier did have a bit of good news.
Safety Harrison Smith, out since Oct. 13 with a toe injury, could be activated off injured reserve to play on Sunday at home against Philadelphia. Smith was placed on injured reserve with the team's designation to return. He returned to practice on Nov. 29.
"We'll make a decision on Harrison at the end of the week," Frazier said. "Probably Friday or Saturday we'll make a decision."
