Johnson, the most valuable player at the Southeastern Conference Tournament earlier this month, is not expected to miss any game action due to the injuries, which were sustained midway through LSU's 80-69 win over Wisconsin-Green Bay on Monday in Eugene, Ore.
Johnson underwent two CAT scan's as well as seeing a facial specialist on Tuesday morning, just hours after the Lady Tigers returned from its trip 5-hour plane trip from Oregon.
Johnson, a 5-3 junior from New Orleans, missed most of the second half after taking an incidental elbow to the right side of her face with 12:45 left in the contest. Johnson's attempt to return to the contest three minutes following the injury was unsuccessful. Johnson finished with seven assists in 25 minutes of action against the Phoenix.
"We're very optimistic about her being able to play in our next game," LSU coach Sue Gunter said. "She really took a shot to the face. We're going to listen to what the doctors are saying and right now we'll just take it day-by-day."
Gunter said Johnson could return to the practice floor by Friday. The Lady Tigers don't play again until Sunday when they face the Louisiana Tech-Ohio State winner in the Sweet 16 in Palo Alto, Calif. When Johnson does return to the court, she'll be wearing protective goggles.
Johnson has started all 32 games this year for the 29-3 Lady Tigers. She's averaging 10.1 points, 5.7 assists and 3.4 rebounds for third-ranked LSU.
