1. Chris Johnson diagnosed with fractured tibia

An injury that was originally reported as a mere knee bruise took a turn for the worse upon further examination. Chris Johnson is going to be out indefinitely, which I’m not happy about as he was a weekly fade for me (as noted in Leverage last week). I am happy about a chance to see what David Johnson can do, as this was one of the most exciting athletes in the draft.

Johnson ranked second among 2015 running backs in the 3-cone, broad jump and vertical. He was 4th in the 40-yard dash and bench press. Johnson has translated those athletic gifts to the NFL level, scoring seven touchdowns on just 54 touches in the regular season and netting 119 total yards on 29 preseason touches. With Andre Ellington (turf toe) very iffy, Johnson is a good bet for 15-19 touches against the Rams Sunday. He’ll be backed up by only Stepfan Taylor and maybe practice squadder Kerwynn Williams, and costs just $3400.

2. Rob Gronkowski expected out Sunday, Danny Amendola likely back

Monday brought reasonably good news for Rob Gronkowski. He isn’t expected to play against the Eagles Sunday, but he’s only week-to-week due to a “knee strain.” His return will largely be based on pain tolerance. Without Gronk, Scott Chandler is firmly in play for $2500 on DraftKings. His role was already expanding and he set season-highs in snap rate (80.6%), routes run (39), catches (5), targets (11) and yards (58) Sunday night.

Meanwhile, the Patriots cut Chris Harper on Monday in the wake of his muffed punt against the Broncos. To me, that’s great news for Danny Amendola’s (knee) status. If Amendola is truly close to 100 percent, he’ll play somewhere close to 90 percent of the snaps in a dream matchup against the Eagles. Amendola costs $4700. Remember that he posted a 9-117-0 line on 12 targets before leaving early in the fourth quarter of Week 11.

3. Rishard Matthews broke ribs in loss to Jets

Matthews took a nasty shot from Jets S Calvin Pryor Sunday and fractured multiple ribs. It creates an opening for the Dolphins to take a long look at first-round rookie WR DeVante Parker. With Matthews only playing three snaps Sunday, Parker got 61-of-75 compared to 54 for Kenny Stills and 19 for Greg Jennings. Parker should be on the field for all two-wide sets in a tasty matchup against the Ravens in Week 13. He’s very interesting at a meager $3300.

4. Jaguars say they’ll get T.J. Yeldon more involved in red-zone

One of the big problems with the T.J. Yeldon play last week was his meager red-zone opportunity. Yes, I fell victim to it as well. But this is a team that is extremely pass-happy, especially near the goal-line. They had 11 red-zone snaps against the Chargers and Yeldon got zero of them. Over the last five games, the Jags have 51 red-zone snaps and Yeldon has eight red-zone touches there. It’s too late now for a lot of people (including me), but it’s something to keep in mind when considering the rookie – even as the Jags claim they’ll get him more involved in the red zone going forward.
