Lions head coach Dan Campbell said LaPorta (shoulder) didn't practice Wednesday, Eric Woodyard of ESPN.com reports.
LaPorta exited this past Sunday's 26-23 win at Houston due a shoulder injury that eventually was termed an AC joint sprain. On Monday, Campbell called LaPorta day-to-day, and the coach used the same term to describe the tight end Wednesday. LaPorta will have two more chances this week to put himself in a position to be available Sunday against the Jaguars.
