Kraft (back) is listed as questionable for Friday's contest versus the Eagles in Brazil, Wes Hodkiewicz of the Packers' official site reports.
The Packers included Kraft on their estimated injury report Wednesday due to a back issue, which wasn't evident at Tuesday's practice. He proceeded to go through a limited session to cap Week 1 prep, and his game status now won't be confirmed, one way or another, until 90 minutes before an 8:15 p.m. ET kickoff. Any reps that Kraft cedes in Friday's game would filter down to fellow second-year TEs Luke Musgrave and Ben Sims.
