    list: A list of tuples containing the 10 most common words and their counts.
    Axes: The matplotlib Axes object of the bar chart.
You should write self-contained code starting with:
```
import re
from collections import Counter
import matplotlib.pyplot as plt
def task_func(text):
```

## Instructions

Your solution should be saved to:
```
/workspace/solution.py
```

The solution will be tested automatically against hidden test cases.
