Alonso (knee) received the return designation and should practice this week, Field Yates of ESPN reports.
The 30-year-old has been on the PUP list since training camp while recovering from ACL surgery in January, but his return to practice indicates he should be ready to go soon. Alonso played only 290 defensive snaps and had a career-low 31 tackles in 13 games last season, so he isn't guaranteed to have a significant role once activated.
