"He's played well," said White Sox manager Robin Ventura, terming Dunn's first-base defense somewhere between Gold Glove-caliber and a liability. "It's that and him getting out there.
"It's better for him to play than it is to DH. People think it's easy to DH, but it's not. The rhythm and the timing of playing, I think that helps him to get out there and play."
Konerko was scheduled to check in with the White Sox and head athletic trainer Herm Schneider on Saturday, but Ventura said that the captain would not be traveling to Toronto with the team Sunday night. He's not supposed to do anything, so Konerko's absence could conceivably last longer than seven days before MLB approves a return.
"They're going to have to go through their channels of testing him and sending people to make sure he's all right and tests fine and is going to be able to play," Ventura said. "I guess it's more how he sleeps. I think he had problems sleeping the first night and even going from there he's going to have to start moving around and running again.
"There's going to be little steps he's going to have to take to get cleared. I don't think it's going to be as easy as picking seven days and thinking that's going to be it."
Konerko sustained the concussion when struck in the right temple by Jarrod Dyson's left elbow during a seventh-inning play at first Tuesday against the Royals.
