Minnesota Vikings wide receiver Percy Harvin is officially listed as doubtful for Sunday's NFC North divisional contest against the Detroit Lions, according to the team's injury report Friday.

Harvin has not practiced all week and is believed to have slim chances of taking the field on Sunday. Also listed as doubtful on the team report is defensive tackle Letroy Guion, who is battling a foot injury and was a limited participant in Vikings practice on Friday after not practicing at all earlier in the week.

Running back Adrian Peterson, though he did not practice Thursday due to an illness, was a full participant on Friday and is listed as probable.

Cornerback Antoine Winfield, offensive tackle Matt Kalil and fullback Jerome Felton were all limited participants in practice on Wednesday and Thursday, but after all three of them fully practiced on Friday, they were listed as probable to play in Sunday's home game against the Lions.
