"I don't expect him to be back in five days, to be honest with you," said Guillen, who did acknowledge Dunn is feeling better with each day. "He's got to hit. He's got to show me, he got to show the doctors, the trainers, [general manager Ken Williams]. He's got to show a lot of people.
"He's got to show his hitting coach. When everybody says he's ready, he's in the lineup. Obviously, we want him in the lineup, but we've got to be careful."
When asked if he would think about using Dunn as a pinch-hitter on Friday, if the game was on the line, Guillen said he would rather lose one contest than risk losing Dunn for another month.
